2.20. Removal and installation of a head of the block of cylinders on the removed engine

GENERAL INFORMATION

Prevention

Removal of a head of the block of cylinders make on the cold engine. At installation it is necessary to use new bolts of fastening and new laying of a head of the block of cylinders. At установ ке cases of a camshaft it is necessary to use hermetic. The specified moments of a tightening can be applied only to later bolts. When using bolts of early types specify the tightening moments at the dealer of Opel.


Removal

The head of the block of cylinders can be removed together with collectors or before removal of a head of the block of cylinders it is possible to disconnect from it collectors.

PERFORMANCE ORDER
1. Remove a gear belt and a camshaft pulley.
2. Unscrew two bolts, fixing a back casing of a gear belt to the camshaft case.
3. Mark and remove high-voltage wires from candles and the ignition coil. Uncover the distributor of ignition and, at existence, disconnect from the distributor the electric socket.
4. Remove a hose of ventilation of a case from a branch pipe on the camshaft case. Unscrew a bolt, a fixing arm of fastening of a pipe of ventilation of a case to an end face of a head of the block of cylinders.
5. Check that all hoses, pipes and wires are disconnected from a head of the block of cylinders.
6. Unscrew bolts of fastening of a head of the block of cylinders, working on a spiral outside inside, unscrewing bolts on a turn half for each pass before complete unscrewing of bolts (see fig. Sequence of unscrewing of bolts of fastening of a head of the block of cylinders on the SOHC engine).
7. Remove from a head of the block of cylinders the camshaft case.
8. Remove yokes, blocks of axial pressure and hydraulic pushers and place them in the corresponding container filled with oil so that at installation they became everyone on the place.
9. Remove a head of the block of cylinders.
10. Remove laying of a head of the block of cylinders.

Preparation for installation

PERFORMANCE ORDER
1. Interfaced surfaces of a head and the block of cylinders should be absolutely pure. For their cleaning use a firm plastic or wooden scraper. When cleaning be careful, as the aluminum alloy is very easy for damaging. Check that the deposit did not get to oil and water canals. It is especially important for greasing system as the deposit can block supply of oil to engine components. If necessary clear channels.
2. Check interfaced surfaces of a head and the block of cylinders on existence of notches, deep scratches and other damages. If defects small, they can be removed with machining. But at major defects of a detail are subject to replacement.
3. Using a metal ruler and щуп, check planeness of interfaced surfaces.
4. Clear openings under bolts in the block. Bolt screwing up in the opening filled with oil can break off the block because of hydraulic pressure.
5. Replace bolts of fastening of a head of the block of cylinders irrespective of their condition.

Installation

PERFORMANCE ORDER
1. Check that the piston of the first cylinder is in the top dead point. Check that two directing pins are established in the block of cylinders.
2. Establish new laying of a head of the block of cylinders so that marking of TORAHS/OBEN was directed up.
3. Establish a head of the block of cylinders on directing pins of the block of cylinders.
4. Establish on a head of the block of cylinders hydraulic pushers of valves, blocks of axial pressure and a yoke on the same places where they were before removal. Before installation grease nests of hydraulic pushers with engine oil. At installation new гидравли chesky pushers place them in the container with engine oil and manually compress several times for filling with their oil. Grease interfaced surfaces of hydraulic pushers, blocks of axial pressure and yokes with greasing on the basis of a molybdenum disulfide.
5. Temporarily establish a pulley of a cranked shaft and check that adjusting labels of pulleys are combined with indexes.
6. Apply a thin film Opel No. 994714 hermetic on interfaced surfaces of a head of the block of cylinders and camshaft cases, then establish the camshaft case.
7. Establish new bolts of fastening of a head of the block of cylinders with washers and screw in them by hand.
8. Gradually and consistently in four stages tighten bolts of fastening of a head of the block of cylinders on a spiral from within outside.
9. Further installation is made in sequence, return to removal taking into account the next moments.
10. Check correctness of installation of high-voltage wires on spark plugs.
11. Establish a pulley of a camshaft and a gear belt and adjust a tension of a gear belt.
12. Establish a collector on a head of the block of cylinders, thus use new laying of a collector.
